(meteorobs) successfully Compiled the existing "METEOR" Code

Wed Oct 17 09:50:22 EDT 2012

The program is expected to "find" the computer sound card without 
anything special needed in this.
The audio signal from the receiver (in CW or SSB mode) is connected to 
the sound card microphone connection.

The one who reported that it works in iMac needed only a double click to 
get it running. He allready had some experience of this maybe from 
Linux, do not see this mentioned in his email on this from the year 
2009, that I now searched to read what he wrote on this. In any case one 
other person has reported that it works in Linux.

The volume in the receiver and/or computer microphone settings are 
adjusted to a reasonable level, not to have the sound card much of 
overload or non linear behaviour, and neither too weak of a signal.
The program has its own volume settings (for each defined spectrum 
window), but these affect only in the program internally and do not 
adjust the sound card sensitivity. The sampling rate of the sound card 
can be adjusted from the program, among with the (In the program) used 
buffer sizes for FFT analyses.

One starts the program and eiher originally makes his own definitions 
for the program internal spectrum windows (and saves these for further 
use) or loads ready made "session-definitions". Only one common sampling 
rate for all the used spectrum-window can be in use, but different sized 
buffers is ok.
